Abstract

The a.c voltage (U) to be measured is applied to a Pockel element (3) and alters the polarisation of measuring light (L) passing therethrough. The measuring light (L) is divided into two differently polarised partial light signals (LS1, LS2) after passing through the Pockel element (3). The partial light signal (LS1, LS2) are converted into electric intensity signals (S1, S2). A function value (f) for the temperature is derived from at least one intensity signal (S1). A standardised intensity signal (P1) is formed from at least one of the intensity signals (S1). An intensity variation and temperature-compensated measurement signal (M) is obtained from with the function value (f) and the standardised intensity signal (P1).
